Thread: New stone

Hello, I found this stone at a flea market on Sunday, is a big chunk of stone is 7 6/8 x 2 6/8 x 1. Is a blue grey stone with some figures inside, not very hard, slurry easy , darker slurry but when is dry the slurry is white. Is a slow stone, when honing with slurry is smell like mud. I can't figure out what kind is, please let me know your thoughts.

Back up and take some pics, They're all close up's. It'd be helpful to see the entire stone....It looks like a Chinese 12k or Phig, and the size/color is right.....

Thank you. Here are more pics. Is not pigh a hard stone? This was not so hard to flat.

You say when honing it smells like mud. Have you used it on a razor? If so at what step and how did it work

And does it bead water?

I used on a razor after the bevel was set, I can't say what grit is, the razor did get sharper, but it won't pass HHT. The water is stay on the stone, or to say the stone is not thisty.

No idea, Sorry....Maybe someone else will chime in...

I am kinda thinking slate but not with a lot of confidence.

Reminds me of slate also, kind of has a similar sheen and figure to a vintage yellow lake oilstone that I have.

It looks like slate, but it could be a phig. Not all phigs are hard. I have one that will raise a slurry by itself when honing (which I don't think is a real charming trait for a phig to have). I sold a much better (and harder) one in the classifieds a couple of weeks ago. I've only had those two, but they were much different stones in terms of how easily they let go of their grit.

Thank you gents, I will test it more and let you know the finds,
